HEADLIGHT.

Specification of Letters Patent.

Patented Aug. l, 1916.

Application filed February 8, 1916. Serial No 77,012.

class used commonly on automobiles, and

the like vehicles, and my purpose is to provide a light, cheap and serviceable housing for the lamp and reflector of such headlights, as well as novel means for removably securing the front glass in such housings.

In order to explain my invention clearly I have provided the annexed drawings in which Figure 1 is a front elevation of a'headlight embodying my present improvements and Fig. 2 is a side elevation of the same with the housing partly broken away to disclose the interior construction. Fig. 3 is a detached, circumferential face view of a ring by means of which the front glass is removably secured inplace in the reflector housing. Fig. 4 is a relatively enlarged, sectional, view of engaging portions of the housing, the front glass, and the means for locking the said glass in the housing.

Referring to these drawings the letter (1 indicates the reflector housing, or outer shell, the same being formed of papier mach, or so called indurated fiber, which is cheap, strong, light: and serviceable, the reflector proper being denoted by the letter Z). The papier mach wall of the housing, surrounding the open front end of the housing, is ,re-

inforced, as at a and is rabbeted interiorly as ate to receive a metal ring 0 whose outer face is formed with an annular channel in provided with a like number of pins or screws 11. which enter the said springs when theseveral parts are assembled (see Fig. 4:)

the said springs then acting with a constant tendency to force the ring 0 outward.

Outside the disk. of glass e is located the retaining ring 2', said ring being formed with two or more undercut notches la which serve, in connection with pins m in the housingv a, as bayonet joints to look the said ring in its home position in the housing.

In the operation of assembling the several described parts, the springs g are first dropped into the holes f and the ring 0 is placed in the rabbet a with the pins h entered in the said springs. The disk 6 of glass, is then placed in the rabbet, against the packing ring d, and the retaining ring 21 is placed against the glass and the assembled ring 0, glass e and retaining ring'i, are forced into the rabbet, against the resisting force of the spring 9, until the bayonet joint notches is can be interlocked with thepins m. The glass disk 6 is then firmly seated against the packing ring (l which together with the springs 9 provide a yielding support' for said glass to relieve the rigidity, and danger of breakage, which would result if the glass was seated immediately in the rabbet a and, at the same time a dust-proof joint is provided between the glass and the reflector.

Thecustomary ears n, (by means of which my described papier mach housing may be supported on the vehicle) I provide by riveting to the opposite sides of said housing suitably shaped sheet metal plates, as seen in Fig. 2.

My described headlight I find, in practice,

is both serviceable and highly satisfactory.

Having thus described my invention, I

claim as new and wish to secure by Letters Patent A headlight comprising, in combination, 'a papier mach housing rabbeted at its open end, springs in said rabbet, a packing ring seated on said springs, a disk of glass seated on said packing, and means for removably securing the said glass in said rabbet.
